What is VERILAST Technology for Knees?
VERILAST technology is the first device to combine an OXINIUM
Oxidized Zirconium femoral component with a highly crosslinked ultra-high molecular weight polyethylene (UHM-WPE) tibial insert to form an advanced TKA bearing.
• The first knee lab tested to demonstrate wear performance sufficient for 30 years of use under typical conditions*
• Offers the younger, more active patients a TKA solution designed to address their increased expectations for wear performance.
• An often used solution in total knee replacement for patients with metal sensitivity.
When used with our
Total Knee System
, it demonstrated an impressive 81% reduction in wear in simulated lab testing compared to conventional materials. Plus, wear simulation indicates that the LEGION Cruciate Retaining Knee System with VERILAST Technology may last up to 30 years of wear - that's twice the current industry standard of 15 years.

*Based on in-vitro wear simulation testing, the LEGION
Primary Knee System with VERILAST
technology is expected to provide wear performance sufficient for 30 years of actual use under typical conditions.
The results of in-vitro wear simulation testing have not been proven to quantitatively predict clinical wear performance. Also, a reduction in total polyethylene wear volume or wear rate alone may not result in an improved clinical outcome as wear particle size and morphology are also critical factors in the evaluation of the potential for wear mediated osteolysis and associated aseptic implant loosening. Particle size and morphology were not evaluated as part of the testing.
